The entire book will eventually be available, probably sometime over the next month or two. The rate at which I can upload new chapters depends primarily on how busy things are at my day job.
Please Note: If you downloaded the audio files here on 2011.11.23 or earlier, I have since re-recorded the Foreword by Tim O'Reilly so as not to be *quite* so casual in tone (read: slow in tempo). Please consider replacing the old file with my updated version.
